Hi there,
Firstly I would just like to say that whilst we have only been using
Elda and Fuseki for about a year, we have until now been really very
happy with them. Excellent stuff :-)
Which versions?
And is this using sub-SELECTs enabled in Elda?
IIRC that will replace the nearly 10,000 cases of UNION with the SELECT
that generated it in the first place, which is much (much) shorter.
Unfortunately, today, we have a query that is generated by Elda and
POST'ed to Fuseki (https://github.com/epimorphics/elda). The query is
about 1.4MB!
Unfortunately this query causes Fuseki to throw a
java.lang.StackOverflowError. The only other post I found on the
mailing list which looks similar was from 2011
http://markmail.org/message/pwzdrcn7lnkqra35 but there was no follow
up to it.
Have you tried increasing the stack? What happens?
Unfortunately, we really need to solve this issue quickly. I am not
opposed to getting my hands dirty in the Jena code base if someone can
tell me what needs to be done, and support me when I have questions.
But hopefully there is some sort of quick workaround? So then, what
are my options chaps?
You may access the stack trace here:

and the query that caused the exception here:

Sorry for the use of DropBox, book the Apache mailing list manager
kept rejecting my post as it was too large otherwise.
Thanks Adam.
Andy
